Activatable Photoacoustic Probe for Imaging Infection: Gold Nanorod Dissociation In Vivo Reports Bacterial Protease Activity.
Article in ACS nano, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
We present a strategy for constructing activatable photoacoustic imaging (PAI) probes for in vivo enzyme activity measurements, based on a dissociation strategy previously applied to in vitro sensing. Unlike conventional nanoparticle aggregation strategies, dissociation minimizes false positives and functions effectively in complex biological environments. Overcoming the challenge of dissociating nanostructure aggregates, which arises from the strong van der Waals forces at short distances, we demonstrate the controlled assembly and dissociation of citrate-capped gold nanorods (AuNRs-citrate) using a diarginine peptide additive and a thiolated polyethylene glycol (HS-PEG-OMe), respectively. This assembly dissociation mechanism enables precise control of the optical and photoacoustic (PA) properties of AuNRs in both in vitro and in vivo settings. Building on these findings, we engineered an enzyme-sensitive PAI probe (AuNRs@RgpB) composed of AuNR assemblies and a PEG-peptide conjugate with a protease-specific cleavage sequence. The probe detects Arg-specific gingipain (RgpB), a protease expressed by
